Yes, but we have to calculate the distance traveled on a Flat Earth Map. The range is 11,000 km for the Pasific routs not 7000 km.

I don't understand what calculation you're asking for.

11,000 km is from where to where? Is that the maximum range of the aircraft? The range you gave earlier, 7800 nautical miles, is close to 15,000 km.

Calculate the distance traveled from where to where? From the last known point north of Sumatra to the search area west of Perth? From the last known point to the site the debris was found? Something else?

Which flat earth map? The often used one with the north pole at the center and the rim about 20,000 km away? A different map?

The debris was presumably carried from the crash site to where it was found by ocean currents, so the distance to the location where debris was discovered is only loosely related to the location of the crash.

Please clarify.
